Note 2. All voltages are with respect to ground.
Note 3. VSS1, VSS2 and VSS3 must be connected to the same analog ground plane.

Note 6. This power is the AK4695 internal dissipation that does not include power dissipation of externally connected
headphone and speaker. The maximum junction temperature is 125C and θja (Junction to Ambient) is 42.5C/W at
JESD51-9 (2p2s). When Pd =920mW and the θja is 42.5C/W, the junction temperature does not exceed 125C. In
this case, there is no case that the AK4695 is damaged by its internal power dissipation. Therefore, the AK4695
should be used in the condition of θja ≤ 42.5C/W.
WARNING: Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
